People need to face the fact that Obito without Kamui is only Jonin level, he relies too much on Kamui and as a result his skill suffers. That's why a complete ninja like Kakashi can out best him in combat.
Everyone already knows this, you're not telling anybody anything new. & relying on kamui is not a bad strategy because there are barely a handful of people who even have a chance at touching obito, let alone killing him.
Kakashi is complete in terms of his overall skills. Nin, gen, tai, etc.. Are all above average.
Obito's ninjutsu is god tier, & he can combine it with his other abilities to empower them even more. However the
key here to obito's defeat was taijutsu, which he has no need to train because he can become intangible. Because kakashi is more well-rounded, he was able to best obito in this regard. In the ninjutsu battle kakashi lost, & in the genjutsu battle they tied. Kakashi finally ended it because obito had no access to the ability that empowers his taijutsu to kage level.
This is why he lost, his taijutsu was lacking & kakashi took advantage, that's it.
and even if Obito had access to Kamui, Kakashi knows exactly how it works and how to counter it with his own Kamui.
No, they had a kamui battle, kakashi lost.
It took 4 ninja above kage level in order to even figure out the jutsu, & even if he does know its workings, tell me how he can stop the gedo statue? or human path? or uchiha kenjin? or the shurikenjutsu barrage? or the juubi sized katon? or mokuton? (I know you said it would be useless but it caught BM naruto momentarily so that point is moot). These are all part of his ninjutsu arsenal & he didnt use any of it during their battle, only a minuscule katon & chakra rods.
Kakashi > Two tome Obito (Obviously)
MS Obito > Sharingan Kakashi (Obviously)
MS Kakashi > MS Obito (LOL)
MS Kakashi > Rinngan Obito (without paths) (Gedo statue/Uchiha kaenjin/human path/etc...^^)
Jubito > MS Kakashi. (Obviously)
And that's the whole truth and nothing but the truth. Kishi has shown them fight 1 vs 1 in a fair fight of 2 shinobi and there was only one winner, why argue with it?
Wrong, that was a fight where obito had no access to kamui & his best ninjutsu. 1v1 obito uses intangibility & kakashi can't touch him, how does kakashi hit obito when he can't even lay a finger on him outside of kamui land? He can't,
& that's the truth.
